PCCD / Fs from incineration medical care waste in east Algeria

Abstract

The incineration of waste from medical care waste , pharmaceutical and  DASRI: (wastes infectious Risk Care Activities)  is just beginning to develop in Algeria and the pollution by this toxic waste is caused by PCDD / F which must be monitored and quantified because these pollutants cause a great controversy on the treatment of our hospital waste by  our incinerators.  Knowing that Algeria does not have high-tech incinerators for the treatment of incineration gases and does not have much experience in this waste treatment technique.

This study presents firstly a qualitative and quantitative analysis of semi-volatile organic compounds (PCDD and PCDF), their concentrations were evaluated by monitoring the emissions of an industrial waste incinerator (Société ECFERAL). PCDD / F was collected by active sampling using an isokinetic sampler in the incinerator stack gas release. Following treatment A1, a high level was recorded for OCDD of 2,987 ng / m3 of gaz emission DASRI .We have studied afterwards the exact location of PCDD / F formation in the incinerator, in order to better control technology, which led us to install another treatment(gas adsorption column)in parallel with the old, to reduce these pollutants at the exit of the chimney, there is had a decrease of more than 40%following treatment B2.
